timezone data: update to 2016c

Update timezone data to 2016c.

2016b: http://mm.icann.org/pipermail/tz-announce/2016-March/000036.html

   Changes affecting future time stamps

     New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
     Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04
     on 2016-03-27 at 02:00 local time.  They need distinct zones since
     their post-1970 histories disagree.  New zone Asia/Barnaul for Altai
     Krai and Altai Republic, Russia, which will switch from +06 to +07
     on the same date and local time.  Also, Asia/Sakhalin moves from +10
     to +11 on 2016-03-27 at 02:00.

     As a trial of a new system that needs less information to be made up,
     the new zones use numeric time zone abbreviations like "+04"
     instead of invented abbreviations like "ASTT".

     Haiti will not observe DST in 2016.

     Palestine's spring-forward transition on 2016-03-26 is at 01:00,
     not 00:00. Guess future transitions will be March's last Saturday
     at 01:00, not March's last Friday at 24:00.

2016c: http://mm.icann.org/pipermail/tz-announce/2016-March/000037.html

   Changes affecting future time stamps

     Azerbaijan no longer observes DST.

     Chile reverts from permanent to seasonal DST.
     Guess that future transitions are August's and May's second
     Saturdays at 24:00 mainland time.  Also, call the period from
     2014-09-07 through 2016-05-14 daylight saving time instead of
     standard time, as that seems more appropriate now.

Note for Openwrt usage:

Either musl or busybox does not like the new timezone format.
Although the rule looks ok in /etc/TZ, timezone is interpreted wrongly
by date, uptime etc. "Old timezones" are handle correctly, but these
new "<+04>-4" style zones do not work. Example below:

Europe/Helsinki
 root@OpenWrt:~# cat /etc/TZ
 EET-2EEST,M3.5.0/3,M10.5.0/4
 root@OpenWrt:~# uptime
  11:00:52 up 18:17,  load average: 0.43, 0.13, 0.11
 root@OpenWrt:~# date
 Wed Mar 30 11:00:55 EEST 2016

Europe/Astrakhan
 ( Time is showed as GMT instead of the correct zone and
   zone name is parsed wrongly )
 root@OpenWrt:~# cat /etc/TZ
 <+04>-4
 root@OpenWrt:~# uptime
  08:02:52 up 18:19,  load average: 0.17, 0.18, 0.13
 root@OpenWrt:~# date
 Wed Mar 30 08:02:59 +04>-4 2016
